Audiograms of 11,577 made Marine officers and enlisted personnel are analyzed by age group and level of hearing for six frequencies: 500, 1,000, 2,000, 3,000, 4,000, and 6,000 Hz. Speech reception thresholds are determined for the average of 500, 1,000, and 2,000 Hz as recommended by the American Academy of Ophthalmology; high-frequency thresholds are determined for the average of 3,000, 4,000, and 6,000 Hz. Hearing impairment (greater than 25 dB ISO) for the speech frequencies is between 0.6% and 5.9%; for the high frequencies the range is 3.4% to 76.5%. For the high frequencies the largest increase in impairment is in the age group 35 to 44 years. No difference in the percentage distribution of hearing impairment is found between a statistically comparable group of civilians and Marines. This is in sharp disagreement with the hypothesis that a greater degree of hearing loss would exist in a military population exposed to more noise than a civilian population. Hearing impairment in the high frequencies caused by noise exposure is a problem of significant magnitude, especially above the age of 35, and may have an effect on speech intelligibility. However, the magnitude of the problem seems to be the same in the military and civilian populations studied.
对11577名现役海军军官和士兵的听力图按年龄组和六个频率（500、1000、2000、3000、4000和6000赫兹）的听力水平进行了分析。按照美国眼科学会的建议，确定了500、1000和2000赫兹平均频率的言语接受阈值；确定了3000、4000和6000赫兹平均频率的高频阈值。言语频率的听力损伤（大于25分贝ISO）在0.6%至5.9%之间；高频的范围是3.4%至76.5%。对于高频，损伤增加最大的是35至44岁年龄组。在统计学上具有可比性的平民组和海军陆战队之间，未发现听力损伤百分比分布的差异。这与以下假设形成了鲜明的分歧：与平民相比，暴露于更多噪音的军事人群中会存在更大程度的听力损失。噪音暴露导致的高频听力损伤是一个相当严重的问题，尤其是在35岁以上，并且可能会对言语清晰度产生影响。然而，在所研究的军事和民用人群中，这个问题的严重程度似乎是相同的。
